Armenia is notable for its wild pear diversity, which includes a large number of globally threatened endemic species. Despite progress in recent studies there still remains, however, a lack of data on the distribution and population sizes of some species, and any threats to them. This information is necessary to assess their conservation status and for the planning and implementation of conservation actions. I present the results of fieldwork in the Vayots Dzor province of Armenia on the globally threatened endemic pear species Pyrus daralagezi Mulk., Pyrus hajastana Mulk. and Pyrus gergerana Gladkova. I report new data on distribution, threats and species biology. I inventoried individual trees, discovering five new individuals of P. daralagezi in Herher sanctuary, rediscovering a population of P. hajastana in its locus classicus 52 years after the first record, and finding a new locality for P. gergerana around the village of Artavan. I make recommendations for the further study and conservation of these threatened pear species.
